Processor

NARA-M motherboard provides the 370pin PGA370 socket that is not backward compatible with ZIF socket-7
processors The Processor's VID pin automatically program the voltage regulator on the motherboard to the
required processor voltage. The motherboard supports processors that run internally at Variable speed clock.

Memory

The motherboard has two, dual inline memory module (DIMM), minimum 16MB to maximum 512MB memory
size. The BIOS can automatically detect the memory type, size, and speed through SMBUS interface between
the core chipset and DIMM module.
The motherboard supports the following memory features
•
3.3V and unbuffered 168-pin DIMM
Voltage detection
Unbuffered detection
•
DRAM interface synchronous with host CPU (66/100/133 MHz) or AGP (66MHz) for most flexible
configuration.
•
Supports FP, EDO, SDRAM, ESDRAM, and VCM SDRAM memory types
•
Different DRAM types may be used in mixed combinations
•
